ABSTRACT
OBJECTIVE:
The objective of this study was to assess the perioperative and long-term outcomes of carotid body tumor (CBT) resection with a multispecialty (head and neck surgery/vascular surgery) approach.METHODS:
Our institutional data registry was queried for Current Procedural Terminology codes (60600, 60605) pertaining to CBT excision. These patient records and operative reports were individually reviewed to determine laterality, preoperative tumor embolization, operative time, estimated blood loss, need for intraoperative transfusion, intraoperative electroencephalogram changes, intraoperative division of the external carotid artery, carotid artery repair, resection of the carotid bifurcation, tumor volume, final pathology, cranial nerve injury, stroke, death, and clinical or radiographic evidence of recurrence.RESULTS:
From 1996 to 2018, 74 CBT resections were identified in 68 patients (41 [60%] females; mean age, 50.83 years). The mean tumor volume was 9.92 ± 14.26 cm3 (range, 0.0250-71.0627 cm3). Embolization was performed by a neurointerventional specialist in 27 CBT resections (36%) based on size (embolization 14.27 ± 16.84 cm3 vs 7.17 ± 11.86 cm3; P = .063) and superior extension. This practice resulted in one asymptomatic vertebral dissection, which postponed the surgery. There was a trend toward greater blood loss in the embolization group (embolization 437 ± 545 mL vs 262 ± 222 mL; P = .17); however, no transfusions were required in any patient. The mean operative time was also significantly longer in the embolization group (198.33 ± 61.13 minutes vs 161.5 ± 55.56 minutes; P = .03). Three resections had reversible intraoperative electroencephalogram changes, one of which occurred during carotid clamping. These changes resolved with shunting. Eight external carotid resections (11%) and 6 carotid reconstructions (8.1%; two primary, two patch, and two primary anastomosis) were required. Malignancy was identified in four tumors (5.4%), accounting for four of the six carotid reconstructions. There were no postoperative cranial nerve injuries, no strokes, no reexplorations, and no deaths. One patient developed transient dysphagia from pharyngeal tumor infiltration. Long-term follow-up (mean, 43 ± 54 months), available in 61 of the 68 patients (89.7%), revealed three (4.4%) recurrences.CONCLUSIONS:
This large, single-institution series demonstrates that a multispecialty team combining two surgical skill sets for the treatment of this rare, challenging condition yields unparalleled low complication rates with short operative times. This approach, including long-term surveillance for recurrent disease, should be considered to optimize outcomes of CBT resection.Palavras-chave
